Scheduling crisis!

<p>Today, my counselor told me I can't take one of my classes next year (AP Chem) because it's already full. So, now I have no idea what to do, but I have a couple of options. I'll be a sophomore next year, btw. The only other AP I'll be taking is APUSH.</p>

<ol>
<li><p>Take advanced chem. The problem is I've already started studying chemistry (even though I'm not supposed to) so I would probably get by the first semester without trying. Super boring, kind of like biology class this year. I really want to take three science APs in high school 'cause I think it'll prepare be better for college.</p></li>
<li><p>Take chem over the summer (what I originally planned to do), take AP bio, AP physics (not sure which one my school offers), or AP Envi Sci during the school year. I would be taking a class with upperclassmen and I'm not sure if I feel comfortable doing that. I feel like I would come off as being pretentious, cocky, hubristic, etc.</p></li>
</ol>

<p>What should I do?</p>
